CHARLES v. MONSON, or" DULUTH, MINNESOTA.

WINDOW-SASI-I FASTENER.

Specification of Letters Patent.

Patented Feb. 5, 1919..

Application filed May 21, 1917. Seria1No. 169,820.

To all whom it may concern:

Be it known that I, Crmnnns V. MONSON, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful. Improvements in VVindow- Sash Fasteners, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to sash locks for windows. The principal object of the invention is to produce simple and strong means for fastening the upper and lower sash of a window together and securely holding same with the joint between the sashes tightly closed.

Another object is to provide a device of this character having a means whereby the window may be firmly united and locked when the two parts of the sash are somewhat separated-or the window partly open.

These and other objects will become evident in the further description of the devlce. Y

In the accompanying drawings forming part of this application and in which like reference characters indicate like parts,

Figure 1 is a top plan view of the improved lock or fastener uniting the two parts of the sash when closed.

Fig. 2 is a similar view illustrating the catch in its unlocked position.

[Fig 3 is a vertical sectional view through the center line of the bolt of the fastener, and

Fig. 4 is a reducedv front elevation of that portion of the fastener attached to the lower rail of the upper half of the window sash and illustrating in active position, the support for the lower sash when open.

1-1 represents two clips spaced apart opposite each other and fastened by means of screws 2 to the upper face of the upper rail 6 of the lower sash. These clips slidably hold between them, the horizontally reciprocal bolt 3, which is scarfed longitudinally its edges, forming a stepped portion 4 and into which stepped portion the upwardly and inwardly extending lips 5 of the clips project, thus forming a secure and substantial guide for the bolt.

The reciprocal motion of the bolt 3 is limited in both directions by. the virtually adjustable L-shapedbolt 78 operative within the rectangular shaped through slot 9 in the horizontally reciprocal bolt 3.

7 represents the horizontal portion of the bolt 7-8 which is of a size to freely fit within the slot 9 when properly adjusted thereto and as shown in Figs. 1 and 3. The vertical portion 8 of the bolt, and which answers as the operating handle thereof, is hollow as at 10 and in which extends an elongated screw 11, a spiral spring 12 being mounted about the screw 11 intermediate the head thereof and the bottom wall 13 of the'hole, for normally holding the bolt in its depressed position.

The screw 11 passes through the bottom wall 13 of the hole 10 and is screwed into the rail 6 as shown in Fig. 3.

By raising the bolt 78 against the expansive action of the spring 12, it may be brought to a level above the surface of the bolt 31 and turned at any desired angle thereto, as shown in Fig. 2, and allowed to rest upon the upper surface of the bolt 3, during which position of the bolt 78, the bolt 3 may be slid back or forth longitudinally as desired, a suitable projecting handle 14: for such purpose being formed integral with the bolt 3. In line with the slot 9 in the bolt 3 and in the forward end thereof, is a notch 15 having an inclined bottom 16 therein, which inclines upwardly toward the forward end of the bolt, the extreme upper corner of the forward end of the bolt being slightly rounded as at 17 for ready engagement with the cooperating portions of the fastener hereinafter described.

An upwardly bowed catch or keeper 18 is rigidly fixed to the upper face of the lower rail 19 of the upper sash of the win dow by means of suitable screws 20. This keeper is so positioned as to register with the end of the bolt 3 when the two rails 6 and 19 are o posite each other, as when the window is c osed.

In the central upper arched portion of the keeper 18 is adjustably mounted a thumb screw 21. When the bolt 3 is adjusted to locking engagement with the keeper 18, the

screw 21 may be extended downwardly into the notch 15 and when advanced in such direction sufficiently far, the end of the screw will engage the inclined bottom 16 of the notch, such engagement having the normal tendency of drawing the two rails, 6 and 19 of the sash, tightly together by virtue of the inclination of the bottom 16 of the notch 15, the same being regulated by the p force supplied to the screw 21, as is obvious.

' gagement with the keeper 18, thebolt 78 must be raised from the slot 9 and preferably allowed to rest transverse the same, which permits of free and unobstructed operation of the window sash.

An additional attachment to the fastener is provided in the form of a hollow rod 22, pivotally mounted as at 23, within one side of the keeper 18, this rod may be of any suitable length and carries, fixed to the free end therof, a collar 24 having a thumb screw 25 therein and which latter is extendible within the interior of the rod. Telescopically mounted within the rod 22 is a rod 26, carrying upon its upper end a rectangular shaped keeper 27 and which keeper may be adjusted vertically to any height desired within the limit of its adjustment and which keeper is designed to register with the engaging end of the bolt 3 when the vertical relation of the two halves of the window sash is changed from normal and whereby the bolt 3 may be made to engage the keeper and thevtwo halves of the sash firmly held in such adjusted position. Within the upper face of the keeper 27 is a thumb screw 28, similar, both, as to construction and office, to that of the. thumb screw 21.

The rod 22 being pivotally mounted within the keeper 18 permits of its being tipped downwardly to one side and resting upon the upper face of the lower rail of the upper half of the sash when not in use, otherwise it may be stood up as shown in Fig. 4: and allowed to rest upon its bent extension 29, which will support it centrally in line 7 for engagement with the bolt 3. From the foregoing it is evident that by the use of the rod 22 and its cooperating parts, the window maybe opened to various limitations and there securely locked when desire While I have shown certain specific forms of construction in illustrating this embodiment of my invention, it is evident that various modifications may be resorted to without departing from the spirit thereof.

Having thus described the invention what I claim as new and desire to secure by Letters Patent is: t

'1; A window sash fastener comprising two opposed guiding members spaced apart and fixed to the upper face of the upper rail of the, lower half of the window sash, a reciprocal bolt intermediate of the guiding members, having an inclined thumb-screw receiving slot in the upper face thereof, a keeper rigidly fixed to the lower rail of the upper half of the sash and adapted to register with the cooperating end of the bolt, means for limiting the longitudinal movement of the bolt and an adjustable thumbscrew within the keeper for cooperative engagement with the inclined slot in the bolt, whereby the two adjacent window sash rails may be simultaneously drawn together.

2. A window sash fastener comprising two opposed guiding members spaced apart and fixed to the upper face of the upper rail of the lower half of the window sash, a reciprocal bolt intermediate of the guiding members, having an inclined thumb-screw receiving slot in the upper face thereof, a keeper rigidly fixed to the lower rail of the upper half of the sash and adapted to register with the cooperating end of the bolt, vertically adjustable spring controlled means for limiting the longitudinal move ment of the bolt and locking same, and an adjustable thumbscrew within the keeper for drawing the adjacent rails of the sash together when in cooperative engagement with the inclined slot in the bolt.

3. A window sash fastener of the character described, comprising a horizontally slidable bolt carried by one portion of the sash, a keeper adapted to register with the bolt and fixed to the opposite portion of the sash and a second keeper supported upon the first mentioned keeper and registerable with the bolt and means for slidably raising and lowering the second keeper to accommodate difierent opened conditions of the window.
